Dynamical Modelling and Simulation of Waste water Filtration Process by Submerged Membrane Bioreactors [PDF]
A mathematical model was developed for the filtration process and the influence of aeration on Submerged Membrane Bioreactors. The dynamics of sludge attachment to and detachment from the membrane, in relation to the filtration and a strong intermittent ...

Production of highly porous glass-ceramics from metallurgical slag, fly ash and waste glass [PDF]
Glass-ceramics composites were produced based on fly-ash obtained from coal power stations, metallurgical slag from ferronickel industry and waste glass from TV monitors, windows and flasks. Using 50% waste flask glass in combination with fly ash and 20%

Aeration and hydrodynamics in submerged membrane bioreactors [PDF]
Membrane bioreactor (MBR) is already a well-developed wastewater treatment process for both municipal and industrial applications. Nonetheless, membrane fouling remains a significant problem for its wider development.

Research Progress of Treatment of Black and Odorous Water Bodies with Aeration Technology
When treating black and odorous water bodies,the current aeration technology is faced with problems such as unscientific aeration design,unreasonable design of parameters such as aeration volume,aeration time,and influence radius,and unclear mechanism of

Aerated bunker discharge of fine dilating powders [PDF]
The discharge rate of coarse powders (mean particle size 500 ¿m) from bunkers without aeration can be described by both empirical relations and theoretical models. In the case of small particles the discharge rate is largely overestimated.
